Directions

The Rothney Astrophysical Observatory (RAO) is located near Priddis, Alberta, about 30 kilometres southwest of the Calgary city centre. It is less than an hour drive from the University of Calgary.

  • Take Macleod Trail south.
  • Go west on Highway 22X, towards the mountains.
  • Continue past Spruce Meadows, past 37 Street, 69 Street and 83 Street to a major intersection where Highway 22X meets Highway 22 (this intersection is illuminated after dark).
  • Turn left toward Millarville (heading south).
  • About 1.2 kilometres south along Highway 22, look for the RAO sign on the west side of the highway. Then in 10 metres, look to the east side of the highway for the large RAO sign and gate. Drive through the gate and follow the gravel road up the hill to the parking area.
